An employee signaling the operator of a loader carrying a bundle
(usually 5) of 600 pound railroad rails was not wearing safety-toe footwear. A serious
violation of section 1517(a) was upheld. The employee was 2-4 feet from the loader forks.
Employers instructions to its signal persons to stay away from the rails in
transport does not obviate the need to comply with section 1517(a). Section 1517(a) is not
unenforceably vague. A Division expert testified that ANSI approved safety-toe footwear
would withstand a minimum of 2,500 pounds of pressure without buckling and thus was
"appropriate" for the hazard posed.
